NIS 2013 and Windows Defender both turned off
I have NIS 2013 v22.214.171.124 running on Win 8 on a (UEFI) booted Lenovo Z580 laptop and it seemed to have worked well from installation in December to some time last month but, now, after reboots, markers soon appear telling me I need to turn on spyware protection and a firewall. The spyware link indicates that NIS and Windows Defender are both switched off but selecting NIS and clicking Turn on changes nothing. The Network firewall link leads to Choose a firewall options but, again, selecting Turn on Norton Internet Security does nothing, even after I select the ensuing Yes, I trust the publisher option. Meanwhile the Action center reinforces the message that both NIS and Defender are switched off, even though NIS itself appears to think all is well, ie it shows no errors.
Anyone have any ideas what has gone wrong here, please, bearing in mind that I ran the Remove and reinstall tool earlier today with no effect on the above situation?
